34.1 Levels of Ecological Study Flashcards
What is the lowest level of ecological Study
organism
Population
having a single species of organisms in a single area where all organisms have ability to mate and produce fertile offspring
Community
all populations in an area (ALL are living)
Ecosystem
the community and the physical environment (biotic and abiotic factors)
What are some things that are included in an ecosystem
temperature, wind patterns, organisms, populations, etc.
Biosphere
all ecosystems
What is the only known biosphere
Earth
Ecology
the study of the relationship of organisms with each other and their physical environment
Biome
all of the RELATED ecosystems on a planet
Biotic Factors
all of the organisms in the area; living component of the environment
Abiotic Factors
the environments nonliving component ; the physical and chemical factors
What are some examples of abiotic factors
temperature, forms of energy, water, and nutrients
Habitat
where an organisms lives (made of abiotic and biotic factors)
Levels of Ecological Study
the 5 levels that ecologists study ecology at
How many levels of ecological study are there?
5
What are the 5 levels of ecological study in order from smallest to largest
1) Organism
2) Population
3) Community
4) Ecosystem
5) Biosphere
What is an example of what an ecologist would study on the organism level?
Adaptions of the Himalayan blue poppy to the freezing temperatures and short days of its abiotic environment
What is an example of what an ecologist might study at the population level?
The size of a population of Himalayan blue poppies, the availability of chemical nutrients, and seed dispersal
What is an example of what an ecologist might study on the community level?
interspecies interactions such as the effect of plant-eaters on poppies or the competition between poppies and other plants for soil nutrients
What is an example of what an ecologist might study on the ecosystem level?
How chemicals cycle and energy flows between organisms and their surroundings (how rapidly does the decomposition of decaying plants release inorganic nutrients)
Landscape
several ecosystems linked by exchanges of energy, materials, and organisms.
